Wearable AR Display Controller Vehicle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) image display systems for wearable terminals, such as smart glasses, often misalign images within vehicle compartments due to inadequate brightness, leading to incorrect marker detection and positioning issues, especially at night or in backlighted situations.
Innovation Solution
An image display controller that estimates the self-location of the wearable terminal, determines a display position based on this estimation, and adjusts the frequency of self-location estimation and display position changes when the terminal is in a vehicle compartment, using a combination of image capture and vehicle communication to prevent misalignment by suspending updates during a predetermined time and displaying images at a fixed position until accurate estimation is re-established.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the self-location estimation frequency is increased to improve image alignment accuracy, then the image positioning precision is improved, but the system consumes more processing resources and may cause confusion to the wearer due to frequent position changes
Solution Approach 1:
The patent applies dynamic adjustment of self-location estimation frequency based on the detected environment. When the wearable terminal is detected to be in a vehicle compartment, the estimation frequency is reduced to a lower frequency. When outside the vehicle compartment, the estimation frequency is increased. This dynamic adaptation resolves the contradiction by optimizing processing resources while maintaining adequate image alignment accuracy for each specific environment.
2Measurement precision
If the display position is frequently updated based on self-location estimation to improve image alignment, then the image positioning accuracy is improved, but the wearer experiences confusion due to frequent position changes in vehicle compartments
Solution Approach 1:
The patent dynamically adjusts the display position update strategy based on the detected environment. In vehicle compartments, the display position is maintained at a fixed position rather than being frequently updated, preventing wearer confusion. Outside vehicle compartments, the display position is updated frequently based on self-location estimation to maintain image alignment accuracy. This dynamic behavior resolves the contradiction between alignment accuracy and wearer experience.
3Measurement precision
If marker detection is performed continuously to improve display position accuracy, then the image placement precision is improved, but the system reliability deteriorates due to misidentification in low brightness conditions
Solution Approach 1:
The patent implements dynamic adjustment of marker detection frequency based on environmental conditions. When the wearable terminal is in a vehicle compartment (where low brightness and backlighting conditions occur), the marker detection frequency is reduced, avoiding misidentification. When outside the vehicle compartment with adequate lighting, marker detection is performed continuously to maintain display position accuracy. This dynamic strategy resolves the contradiction between detection precision and reliability.

AI summary
An image display controller for displaying an image on a display of a wearable terminal is configured to estimate a self-location of the wearable terminal, determine a display position of an image on the display based on the estimated self-location, display the image at the determined display position, detect whether an actual location of the wearable terminal is in a vehicle compartment, and decrease a frequency of estimating the self-location when the actual location is detected in the vehicle compartment to a frequency lower than a frequency of estimating the self-location when the actual location is detected outside the vehicle compartment.
